Are spruce trees transpire more than poplar trees?

Spruce trees generally transpire less than poplar trees due to their needle-like leaves, which have a thicker cuticle and reduced surface area compared to the broad leaves of poplars. This adaptation helps spruce trees conserve water, especially in colder climates. Poplar trees, with their larger leaves, have a higher rate of transpiration as they are adapted to different environmental conditions. Overall, the differences in leaf structure and environmental adaptations influence their transpiration rates.
